DEVICE FOR FORMING FABRICATIONS FROM STRIP MATERIAL Filed Oct. 21, 1949 Patented Mar. 24, 1953 DEVICE FOR FORMING FABRICATIONS FROM STRIP MATERIAL Harry Fuchs, New York, N. Y.

Application October 21, 1949, Serial No. 122,719

11 Claims.

My invention relates to a device for formin fabrications from strip materials of various kinds. It is intended for use with a joining device adapted to join strip material edge to edge, such for example as a sewing machine, and it will be understood that any other kind of joining device may be used.

One object of my invention is to provide an attachment for use with a household sewing machine whereby a woman can make her own hats, handbags, as well as other articles, out of straw braid, felted strip, or fabric strip cut on a bias and folded double to simulate straw braid, thereby effecting considerable economy in the cost of her wardrobe, and savings in household expenditures.

Another object of my invention is to provide an attachment for use with straw braid sewing machines in hat factories and millinery workrooms for automatically holding and controlling a forming strip material fabrication whereby relatively inexperienced persons can make strip material fabrications which heretofore have required the skill of highly experienced operators, and thereby provide for the expansion of the American straw braid hat industry and the export of American straw braid hats to foreign countries.

Further objects of the invention will appear hereinafter.

My invention accordingly consists in the method, system, combinations of elements, arrangements of parts, and in the several steps and relation and order of each of the same to one or more of the others, as will be disclosed herein. The many novel features embraced in this invention are far-reaching in their scope and are applicable in many embodiments other than that described, and I therefore do not wish to be limited except as indicated in the appended claims and within the doctrine of equivalent.

Referring to the accompanying drawing which illustrates one embodiment of my invention as an example, I indicates a supporting plate which is adapted to be secured to the bed plate of a sewing machine by a thumb screw passing through "the hole 2. The offset 3 shown in dotted outline is adapted to fit in a slot in the throat plate of the sewing machine and is inserted therein prior to the insertion of a thumbscrew in hole 2.

The supporting plate I is now aligned for use with the sewing machine, of which 4 indicates the presser foot, 5 the needle, and 6 the gage forming part of the presser foot and adapted to maintain the edge of the forming fabrication in line for the needle 5.

Attached to plate I by means of the rivets or screws '1 and 8, are supports 9 and II] which function as a guiding element. Each of the supports 9 and I0 has at the sides thereof grooves (not shown because Well understood by those skilled in the art), in which are adapted to slide the legs of the U-shaped longitudinally extensive element or component I I having a bend I2 at one end for manual manipulation, and an angular offset I3 secured to the other end by suitable means as for instance by spot welding. The element or component I I slides in the grooves of the supports 9 and I0 transversely of the line of feed with respect to the presser foot 4 and needle 5. It will be noted that leftward of the line of feed toward the needle, the component I I moves transversely of the line of feed at an obtuse angle exceeding and this important feature helps prevent the periphery of the forming fabrication from running off the gage 6.

I4 indicates a needle or equivalent nucleusholding element, upon which is impaled or secured a nucleus such as the disc I5 shown in fragmentary View. The disc I5 may be of buckram, cardboard, or other suitable material.

In its initial position, after it is impaled upon the needle I4 the periphery of the disc I5 rests against the gage 6 of the joining device, and as the unformed strip material I6 is fed to the joining device, successive sections of the strip material are spiralled upon the nucleus I5 thus forming the fabrication indicated in fragmentary view by IT. The unformed strip material !6 passes through the guide I8 secured to plate i and is held in proper alignment for joinder to the nucleus and the forming fabrication by the adjustable gage I9 held in place by the thumb screw 20 which screws into plate I.

As successive sections of strip material are joined to the nucleus by the joining. device and the fabrication II becomes progressively larger, the component I I slides leftwardly in the grooves of the supports 9 and I0; and to maintain the forming fabrication in proper form or shape the stationary arm or element 2|, pivoted in the brackets 22 and 23, sandwiches the forming fabrication between itself and the supporting plate I or the bed plate of the joining device, as well as between itself and the longitudinally extensive element I I. The forming fabrication slides easily between the stationary element 2I and one of the said plates and element II because of the permanent magnet 24, the bottom of which is secured to plate I and the top of which holds the stationary element 2| in proper spaced relation 3 and acts as a stop therefor, the said stationary element 2| or part thereof being made of magnetic material.

In some embodiments I have made one or both of the supports 9 or ID, from magnet material, which I then magnetized, so that there was a frictional drag between the said magnetized support or supports and the longitudinal element or component H as the component I l slid on the said magnetized support or supports during the forming of the strip material fabrication, and this frictional drag helps to maintain the pea riphery of the forming fabrication against the gage 6.

As is easily comprehensive to those skilled in the art, the lateral grooves in the supports 91 and H! are of sufficient height from the bottom thereof so that the sliding component II or the angular offset l3 secured thereto will not come into contact with the supporting plate I or the-bed plate of the associated joining device; also the brackets 22 and 23 and the magnet 26 are of such size and adjustment that there is sufficient clearance between the component II and offset l3 and, the stationary element 21 for the fabrication I1 to move freely during its formation.

It will also be understood that instead of the parts of applicants device being assembled on a nally extensive element, and a stop adapted to maintain a fixed space between the pivoted arm and the longitudinally extensive element.

4. In a device for forming fabrications from strip material, a longitudinal element adapted to hold a nucleus for the joinder thereto of a section of strip material by a joining device, and a guiding element on which the longitudinal element is adapted to slide, one of the said elements being magnetized and the other of the said elements being magnetizable whereby there is a drag on the longitudinal element as it slides on the guiding element during the forming of a fabrication.

5. Ina device for forming fabrications from strip material, a movable element adapted to supporting plate 1 they may be secured directly I to the bed plate of the cooperating joining de vice, and that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
